| Research Abstract |
In the female reproductive tracts, immunological system exists to remove sperm from the tract rapidly after mating or artificial insemination. In the present study, we could make clear that both phagocytotic and chemotactic activities of bovine and porcine polymorphonuclear leukocytes (PMNs), which mainly perform in the system, are stimulated in the presence of fresh serum and decreased in the presence of caffeine, heparin, and seminal plasma. Furthermore, PMNs phagocytize equally both active motile and dead sperm.
